U.S. Apple Stores are pulling overnight shifts to put up new displays and promo materials for the iPhone 4S launch

From MacRumors:

@ifostore is standing in line and shot the above photo where the staff is exchanging old iPhone 4 models with the new iPhone 4S.

Meanwhile, other parts of the world have already seen the iPhone 4S launch, and to massive crowds. Smh.com.au has a running update of the launch in Australia. Even 4 hours after the launch, the line to the Sydney store was described as "appalling" going half way down King Street.
